| titleOfInvention | Device and method for expanding vermiculite |
| abstract | A device for expanding granular raw vermiculite is known, with an expansion tube and one or more burners arranged at one end of the expansion tube, which has at least one fuel gas nozzle for the introduction of a fuel gas and at least one primary air nozzle for combustion air. In order to expand granular raw vermiculite, an oxygen-containing gas is introduced into the entrained flow of a flame. In order to use this to provide a device and a method that allow the throughput of raw vermiculite to be increased and the specific energy requirement to be reduced, it is proposed according to the invention that the primary air nozzle concentrically surrounds the fuel gas nozzle, or that several Fuel gas nozzles are arranged within the at least one primary air nozzle, the burner further comprising at least one subsonic nozzle for oxygen or oxygen-enriched air. The method according to the invention is characterized in that oxygen or oxygen-enriched air is used as the oxygen-containing gas, the oxygen or the oxygen-enriched air being introduced axially into the flame through subsonic nozzles. |
